Caught Red Knotted

The big military academy graduation was happening tonight in Canterlot, and it's citizens along with others throughout Equestria were gathering for the big ceremony that was going to be their families having a member join the ranks of the royal guards in Celestia's service. It was something that only happened once every three years. For the Sparkle household it was a momentus occasion as Shining Armor was graduating with top honors and receiving a high rank to start with. The house was a buzz with Velvet and Night Light trying to get their attire ready, while Shining was working to keep his nerves about him. Little Twilight however was engrossed in her book as she wouldn't be going to the ceremony with how late it would be running.

While the family was busy, the sound of the doorbell ringing was drowned out, with only the small filly hearing it. Twilight walked over and opened the door to be greeted by the sight of the pink alicorn babysitter she enjoyed so much. She was dressed in a purple camisole top, with her baby blue bra straps sticking out behind the small straps of the cami itself. With a green mini skirt that barely reached half way to her knees, and rainbow knee high socks. Her hair was tied back with a blue ribbon in a pony tail that reached to her mid back in length. Twilight let out a scream of delight "Cadance!" She opened her arms into a wide hug for the alicorn.

"Oh my, Twilight." She opened her arms and lifted the filly up so she was face level. "It's good to see you again my silly filly. Now where are your parents or brother?" She heard the commotion going on inside of the homestead and had her question answered as she saw Shining running around half a wreck. "Shiny, I'm here. Let your parents know I've got Twilight." She waved at the white unicorn as his face turned a bright red.

Cadance closed the door behind her and took Twilight over to the couch in the living room and set her down. Taking a seat next to her the purple filly lifted up her newest book to her babysitter. "Look Cadance, I've been learning more magic, this time I'm learning the basics of levitation and it's applications to every day life. It's really cool, watch this." Twilight lit up her horn with a bit of work, as sparks of violet-pink flew out before fully igniting, with the glow taking hold of the book itself and holding it in the air.

The pink alicorn gave a clap at the sight. "Amazing Twilight. Even for something so small you've been doing well with getting a hold of your magic. I see auntie's school is doing some good work."

Before she could continue you, she was cut off by Night Light, Velvet, and Shining coming into the living room and heading to the door. "Thank you so much for watching Twilight tonight Cadance. We wish you could come, but we couldn't find any other person to babysit."

Cadance waved her hands and shook her head, with red glowing in her cheeks. "Its no problem at all. I would have liked to see Shining's graduation as well, but I'm more than happy to spend time with Twily for the night too. Besides its not as often that I get to spend time with her alone now that she's in school."

"Well we'll make sure to bring you some food from the dinner afterwards at least. We'll be home late, so make sure she's in bed by her usual time. She does have school in the morning. Also, if Shining hasn't told you, the new dog is just outside, there is a dog door that he can let himself in and out of so don't worry about that, just make sure he's fed and has water in his bowl. Twilight can show you where we keep the food." Nightlight finished slipping on his black dress shoes. "I know it's a bit last minute to tell you about it, but he's friendly, so don't worry about him too much. We'll see you later Cadance, and Twilight do behave."

The group waved goodbye to the pair as they left the door and got in their car. Cadance turned back to the filly who was already back to nose deep in the book. "So a new dog Twilight. I bet you were excited for that." Cadance poked the unicorn on the nose.

"I was, but he's not to interested in me. He seems to like to follow mom around more than anything. He's only a few days old here so I'm pretty sure he just likes her since she was the one who brought him home." Twilight looked out the sliding door into the back yard. "Just look at him, he seems a bit lazy sometimes with how he just lays on the deck." Twilight pointed to a german shepard just laying in the shaded spot on the deck staring out at the fence.

Cadance scrunched her face with some disapproval of Twilight's choice of calling the dog lazy. "He's not lazy Twilight, I'm pretty sure he's just lonely and hoping for a friend. Maybe you can be his friend if you tried a bit more." Cadance stood up from the couch and headed over to the kitchen. "Besides, it's too nice to be stuck inside all day, how bout we go outside and I'll push you on the swing. It'll give you some fresh air, and the dog can have some company. Now let's get some lemonade and spend the rest of the afternoon out there before we have to come in and eat."

Twilight was up and off the couch in seconds and already headed out to the backyard, leaving Cadance in the house to get their drinks and bring them out. The evening went by fast, and the sun had gone down, leaving the moon to rise and take it's place amongst the skyline. Cadance had tucked Twilight into bed for the night and had gone to the living room to spend out the rest of the night while waiting for the others to come home.

Cadance had turned on the TV and wasn't paying attention to it, and was more interested in her phone as she texted her friends while she waited. As she poked away at the screen on her phone, her arm was met with a small wet object poking around it. She sat up on the couch startled looking around for what touched her before she saw the dog and realized that she had forgotten the dog had even existed in the household. "Phew, jeez, talk about scaring a girl now." She stared down at the dog, with it's mopey face. "Come here you, let's see if we can't cheer you up." She began to rub her hands all over the dog's face, between his ears and under his chin, seeing if she could get his tail wagging.

The dog was more than happy to let the pink alicorn rub his face, giving him a small sense of happiness, but wasn't entirely impressed with her. So he rolled over onto his back and presented his belly to the mare with a small whimper as he stared up at the mare.

"Well now, you seem a bit happy, but I bet you really want some belly rubs now don't you." Cadance got off the couch and on her knees next to the pooch, and began to rub his belly while scratching his chin. "Now that's a good boy. You really just want a friend don't you. A little lonely is all you are." Her hands caressed the canine's form as he made baby talk to him. However she was too busy looking at his face to notice the red rocket rearing from the small sheath hidden in his fur, until her hand bumped into it. When her hand touched the flesh piece instead of the fur, she shifted her head and noticed the veiny red cock sticking out and gasped with shock at the sight. "Oh my. It seems they haven't neutered you yet, that may explain some things. You're probably be aching to mate with another, and Velvet is probably on her estrus and that's why you are following her around."

Laying there and staring at the mare, the dog let out a whimper as his member twitched in the cool air of the living room. When Cadance started to move her hand away from his groin he began to snarl a bit until she moved it back to being close by. He was thirsty for release of his built up sexual tension, and he wasn't going to let this new female walk away from it.

Cadance sat there wondering what she should do. The dog was keeping her there against her will, and didn't want to end up with a serious injury, let alone get the new dog put down for attacking her. She didn't touch the dick directly and worked her hand around the area slowly with caution. Her mind was racing with mixed emotions and feelings as she was scared, but also a bit horny herself since she hadn't gotten to play with her toys for the past few days due to getting her school work done and prepping for her inauguration to being a full fledged princess recognized by Equestria. Her hormones were going wild and filling her head with wild ideas, her heart racing ever harder to make a decision, and her body getting ever closer to the canine cock as her fingers began to brush against the base. Looking at the clock she noticed that it would still be another few hours before they got home, and Twilight was sound asleep, maybe it wouldn't be so bad to have herself some fun with the furry friend.

The dog was embraced by her hand on his red rocket, with her other hand sticking close to his body as she held herself up. Her strokes were slow but steady to make sure no sudden movements would set him off. The dog panted in joy as he felt his meat being treated well by the soft subtle felling of the mare with her gentle caress. Her fingers like magic worked up and down the small length, and picked up the dribbles of pre-cum leaking from his tip as she stroked, using it as a form of minor lubrication. After a few minutes of her work up she began to lap away at the tip with her wet warm tongue, picking up the pre-cum with it's salty taste, with the musky taste of the dog's flesh stick as well. Each lap was welcomed with more and more panting from the dog as it enjoyed the work being done.

The pink alicorn on the other hand was feeling heat building in her own loins, as her pussy got a bit wetter with each lick of the red meat. His dribbles of jizz giving her a weird sensation as she took them in and swallowed them down. Her tongue now getting the vein layout memorized as she covered down to his small knot with her licks. Finally she opened wide and began to suck away on the dick like a popsicle on a warm summers down. Slurping away, and making sure not to let the liquids drop out with her tongue as it swirled around to make sure every inch was in her maw. The full on musky taste of the dog filling her taste buds with the salty sticky fluid that leaked out and consumed any other tastes that remained from the meal earlier in the evening.

Feeling the warmth wrapped around his dick, the dog began to hump as he could while laying on his back in hopes of getting himself finished in the mare in as short as time as possible. However his actions were hindered by his position and with the mare holding onto his chest for balance as she suckled on his sweet meat.

Cadance felt the dog trying to pump himself into her and knew it would be impossible for him to do so. However her body was now on fire, and her pussy was wetting her panties worse then a trip to the local pool. Letting go of the dog's dick, she moved herself sideways and put her ass up and face down for the canine. "I know what you want boy, go on. Ride me like you would any other bitch in heat." She smiled at the canine as she lifted her skirt up and pulled the baby blue panties with pink hearts aside so the dog could have access to her pussy.

The dog, shifted back onto it's feet and began sniffing at the mare's behind. Picking up her scent of lust from her leaking snatch, it sent signals to the dog's mind that she was ready to mate just as much as he was. He lifted himself up onto the mare, placing his paws on her back, while his dick dangled low near her flower. He began to hump away, getting just air before his tip collided with her inner thigh. He struggled to get it in, and kept hitting around his target until Cadance used her hand to guide him into her pussy. The pecker plunged into the warm wet tunnel of her lower lips, as it was wrapped in a tight embrace of lust from the mare.

The pink alicorn let out a moan as she dug her fingers into the carpet that they were laying on, as the dog began to fuck her insides like a wild beast. It's humping raw, and ferocious as the paws held her down, with the dog's teeth inches from her ears as it let out low growls. Its rapid pace plowing her virgin fields causing a slight amount of pain, but nothing she wasn't used to in terms of her toy sizes. Feeling the beast pound her pussy like she was nothing at all, with it leaking it's cum inside her in small amounts. Her body quivered in delight as she felt the dog's knot growing in size, and as his humping became a bit more sporatic as it was getting harder for the knot to come out of her tunnel. Eventually the knot would not pop out and the dog tried it's hardest to keep pumping away at her pussy, until he let go.

Ropey strings of white sticky goo flew directly into the womb of the pink mare, as the dog rested on top of her. His balls draining into her innards with the knot sticking the pair together harder than super glue. The feeling of his release also sent Cadance over her edge as she sprayed her cunny honey all over the floor from her own orgasm from the bestial pleasure. The smell of dog cum and mare fluids started to fill the room as the pair lay there in bliss, unaware of their surroundings at the time.

"Cadance, what's going on here?" A male voice sounded alarmed.

Cadance broke from her bliss quickly to catch sight of Night Light standing in the living room, having just caught sight of her literally screwing the pooch. "Fuck, I'm so sorry Night Light, I didn't mean to... I can... well I mean... I don't know what to say." Cadance's body wanted to wither away and disappear like dust on the wind, as her cheeks filled with burning shame of being seen like she was with an animal stuck to her snatch that was trying to break free from his knotting of her.

Night Light shook his head in disappointment, staring at the pair of them on the floor. "Look, just clean up and go. I can't look at you like this, let alone let you keep watching Twilight if this is going to happen in my own home. I just stopped by to grab something Velvet forgot and this is what I come home to. Please Cadance, I can't trust you after this. There is no way we can have you watch Twilight, and I'm sure Shining Armor won't be to happy about it either."

Tears started to fill Cadance's eyes as she come to terms that she had fucked up something great at the behest of her horny desires. Having to lose Shining Armor, and not be able to see Twilight hurt like a knife in her back. She sobbed out, "Please Night Light, don't tell Shining. I'll do anything you want, just please don't tell him, and let me still be able to watch Twilight. I promise it won't happen again." She crossed her hands, face down in the carpet as she begged and pleaded to the older stallion standing in the room, with his disapproving glance.

The blue unicorn stared at her, his arms crossed as he tapped his fingers on his arm. The mare certainly was in a compromising position, and seemed genuine about her plea. His body was tingling from the sight as it was certainly an erotic thing to behold. This teenager having an animal stuck in her was giving him some wild thoughts as he imagined his wife Velvet in such a position. His thoughts reminded him as well that his wife hadn't been in the mood for loving in a few years since Twilight came along, and maybe this was the time to scratch a few itches. "Alright Cadance, I'll give you a chance." He said as he walked to his recliner chair, and began to undo his pants. "So let's get this straight, you are going to let me have some sex before I go, and I'll keep this all a secret, however if you don't follow through with this, and later requests then I'll just have to let it slip to the family." He pulled out his phone and snapped a few photos of Cadance in the compromised position before setting it down on the side table. He then finished undoing his pants, letting his black shaft hang out while he took his seat. "Now come on over here, and let's see how well you can work that mouth of yours in more than one way. We've got the time to kill before his knot will fade."

Cadance grimaced the thought of having a sexual encounter with Shining's dad, let alone multiple, but he held her life in his hands at the moment and she wasn't going to let that fall through the cracks. Slowly crawling her way over to Night Light with the dog still stuck to her, she managed to raise herself high enough to begin licking away at Night's shaft, with it's salty taste, with a hint of sweat. Her hand took the base of it and stroked at the small portion while her tongue licked away at the tip, getting the taste of his sweet pre-cum on her lips. Small stains of pink were left behind from her lipstick as she began to smooch the length at different parts, while her other hand began to fondle Night's family jewels.

"That's a good girl, getting daddy all nice and ready for a good round. Let's see those tits you got as well." Nightlight moaned as her hand rolled his orbs across all the fingers before dropping back down. He watched as she pulled her camisole off, showing off her matching baby blue bra with pink hearts on the cups with a big red bow in the center of them. Her breasts were certainly smaller than Velvet's but, the nipples were perked up and not sagging down with age that had gained on his wife. "Those certainly are nice Cadance, maybe you should put them to use."

"Thank you, I'm glad you're happy with them, even though they're not as big as Velvet's." She set his shaft between the pair of love pillows and began to stroke them as best as she could with their small B-cup size. Her lips took care of the rest as she suckled on the tip of his dick while the strokes of her breasts took care of the middle. The dog was still in her and struggling to get out as the knot tugged on her pussy's walls, causing her to moan onto the shaft. As she worked her magic, Night Light's phone began to rang with Velvet's ring tone that he had set for her.

Night Light pressed his finger to his lips as he looked at Cadance, and answered the phone. "Hi honey. No no, I'm just getting home, there is a bunch of traffic going on so it's a bit busy. Cadance, she's doing fine, just relaxing with the dog on the floor. She's just keeping him company, he seems to enjoy her presence. I'll be along shortly, just checking on Twilight, and grabbing the gift for Shining and I'll be on my way back. Just order my usual meal if the waiter comes around. I'll be back as soon as I can. Love you too honey." He hung up the phone and let out a moan of pleasure as Cadance had now taken his shaft into her mouth and sucked on it like a lollipop. Her tongue lashing around the edges of his tip, and spiraling around lower.

Cadance groaned as she felt the dog finally break free from her vagina, and leaving a wet trail of his cum down her legs. "I can't believe you just lied to your wife Night Light. It makes me, I don't know how to describe it." Cadance continued with her boob job as she looked up to the stallion sitting back in his chair.

"Simple Cadance, Velvet hasn't touched me in years now and I've got a craving for something. Now drop those cute little panties of yours and let's see about filling your asshole since the dog has claimed your teeny cunt." Night Light patted Cadance on the head.

The pink alicorn stood up, letting Night's shaft free from her maw and breasts. She pulled down her skirt, giving a full view of the hipster cut panties, before turning around and slowly shimming them down with a finger in each hip side. Shaking back and forth as she lowered them, down, showing off more of her bare pink butt, with it's firm but curved shaped. She bent down revealing her dark pink pucker and creamed pussy to Night Light, while she pulled her panties off her leg. She climbed up on the chair facing towards Night Light, as her ass cheeks took hold of his dick between them.

Night Light rubbed his dick up and down between the warm pair of firm cheeks, while he took one of her nipples into his mouth and sucked on them like an infant craving milk from it's mother. Letting go of the first breast he moved to the other sucking on it as well, while Cadance moaned out at the feeling of the suckling of her teats. With a smack of his lips, and his hand against Cadance's butt, He lifted her enough to line up his dick with her tiny starfish before he pushed her down onto the stallion's girthy cock. Her hole split open as it tried to take in the mass, but wasn't used to anything going up there, so some resistance was met as he only gotten a quarter of his length into her. "Mmmm... just relax dear, and let daddy have his way with your tight teeny fuck hole. The more your resist the more it will hurt, so just breath and I'll take it slow for now."

Cadance, gritted her teeth at the pain in her rear, but listened to Night's words. She focused her mind and did some deep breaths as she adjusted to the massive cock slowly slipping deeper into her derriere. Each inch stretched her insides to new levels, but the feeling of his shaft was certainly pleasurable in a different way. Her pussy began to quiver again as she felt another orgasm building from the painful but pleasurable new sensations. "Oh Night Light, it's so big, it hurts, but in a good way." She let out as she finally sank past his medial ring.

The stallion grabbed hold of her firm ass cheeks and gave them a slap with one hand. "That's right, its big, and it's fully of cum ready to stuff your butt. Now let's go for a ride." He took hold of the mare by her hips and began to lift her up, and letting gravity do the rest in pulling her down onto his length. Each time she rose, the fall would plunge him ever deeper into her depths. Her tight tunnel squeezed down on him like a death grip, causing him much more pleasure than Velvet's now loose pussy.

Moving in rhythm with the slaps to her ass, and jiggle of her breasts, Cadance paced herself accordingly to increase her stimulation to the whole ordeal. Helping with the lifting of her body and putting her weight into the downward motion to add the most pleasure, and absorbing as much of Night's cock into her ass. She had gotten used to the size in the backdoor and wanted more, so she took full control of the situation, moving her hips faster instead of fuller, getting his flaring tip to rub against the inner tunnel walls. Her ass was getting redder with each smack to her rump, as hand prints began to form on her ass cheek. "Oh Night, I'm gonna... gonna... cum." She let out a shrill scream as she blew her mare juices and dog cum over the carpet, herself, and Night Light.

Night felt her ass squeeze down as her pussy quivered from her own orgasm, causing him to go over the edge and begin to blow his load deep into her bowels. The sticky smooth fluid attaching to the anal lining and slowly leaking down towards the exit, only to be blocked by the flare of his dick, as more and more blasts of cum filled up Cadance's ass. He took her into a passionate kiss, as their tongues wrestled with each other during their orgasms. The pair in total bliss, as time stood still while Night's balls drained into the alicorn.

After the final twitch, and the last blast of semen into her butt, Cadance broke from the kiss, her eyes glazing over. "That was wonderful Night Light." She began to rest against his chest when a voice was heard coming from down the hallway.

"CADANCE!" Twilight yelled out from her room.

The pair looked at each other, with Cadance taking the front. "Yes Twilight I'm coming." Cadance withdrew herself from off the stallion. His cum leaking from her ass down her legs, while the dog's mixed with it. She quickly got her clothes back on, her panties getting soaked with the semen from the males she had just engaged with. She ran down the hallway to Twilight's room, while Night Light stayed behind in the living room to catch his breath.

After a few minutes, Cadance returned to the living room with Twilight now settled. "Guessing she does need you around still. Shining is going to have a good future wife too. Just remember though, you're at my beck and call for a while or else." He tapped on his phone to remind her of the pictures. "So, how does next week sound to you. The wife and kids are going out to see Manehatten while I'm stuck here working. I think it would be a perfect chance to see what else you can do." Night Light gave a grin to the mare.

Cadance ran her fingers through her ponytail, with red blushing on her face. "That sounds fine Night Light, but you should get back to Velvet before she catches on to something wrong." Her body swayed back and forth with her smitten feelings.

"True, true. Alright we'll see you in a few hours, I'll make sure your meal is freshly made before we leave." He gave the mare a wink before leaving the house with a present in his hands from the closet next to the front door.

The alicorn dropped to the couch exhausted and ready for some sleep. She looked down at the dog curled up on the floor already snoozing. "Well now, it seems you've gotten me into quite a perdicament, and not a bad one at that. Next time we'll have to do it sooner."
